Changing faction names

[AwesomeArcher]

I read the tutorial on changing faction names. I am trying to change the seleucid empire to the sarmatian empire. I edited all the stuff it said to in the tutorial, I changed everything in the strat, expaned, and shared files. but the game still says it is the Seleucid Empire in everything. Is there anything else i have to do?

I can post what the files look like that i edited if you think you could help me out.
